Description

An interactive tablet Technical Field

[0001] The present invention relates to the technical field of microphone board mounting structures, and in particular to an interactive tablet. Background Art

[0002] The existing microphone (MIC) board is fixed by a microphone board bracket, and then fixed to a frame profile by the microphone board bracket. Then, the frame profile presses the foam on the microphone board to achieve the airtightness requirement.

[0003] The airtightness of the existing microphone board is ensured by the foam between the frame profile and the microphone board, which leads to a strong correlation between the microphone board and the frame profile, and cannot be effectively guaranteed when some functions need to be added.

[0004] In addition, most existing microphone boards are fixed to the microphone board bracket by setting snap holes on the board surface. This fixing method also causes the corresponding snaps to break easily during transportation and installation due to the small size of the snap holes, which brings about its own stability problems.

[0005] In view of this, overcoming the defects of the prior art is an urgent problem to be solved in this technical field.

[0006] Application Contents

[0007] The technical problem to be solved by the present invention is that the existing microphone boards are mostly fixed to the microphone board bracket by setting snap holes on the board surface.

[0069] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0070] In the description of the present invention, the terms "inside", "outside", "longitudinal", "lateral", "upper", "lower", "top", "bottom", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.

[0071] The terms "first," "second," etc., used in this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified with "first," "second," etc. may explicitly or implicitly include one or more of such features. Throughout this application, unless otherwise specified, "plurality" means two or more.

[0072] In this application, unless otherwise specified or limited, the term "connection" should be understood broadly. For example, "connection" can mean fixed connection, detachable connection, or integration; it can mean direct connection or indirect connection through an intermediate medium. In addition, the term "coupling" can refer to the manner in which electrical connection is achieved for signal transmission.

[0073] The internal historical version design scheme that the improvement scheme proposed in the present invention relies on is shown in reference figures 1 to 3. The disadvantages are as follows: the airtightness of the microphone board is ensured by the foam 30 between the frame profile 40 and the microphone board 20, which results in the microphone board 20 being closely related to the frame profile 40, and cannot be effectively guaranteed when some functions need to be added. In addition, the aperture of the existing microphone board 20 is relatively small, the space for the clip 50 is insufficient, and the strength of the clip 50 is insufficient. The design of the clip 50 of the microphone board bracket 10 itself requires a certain degree of elasticity, and elasticity and strength are mutually exclusive. Good elasticity means weak strength. At the same time, the existing clip 50 is protruding. During the transportation of the finished product of the microphone board bracket 10, the existing clip 50 is easily squeezed by the outside and deformed or broken, resulting in poor fixation of the microphone board 20. What is also important is that the assembly with the microphone board 20 is carried out by the frame profile 40. The direct problem brought about by this is that once the microphone board 20 completes the version iteration, the corresponding frame profile 40 also needs to be updated. However, the version iteration of the frame profile 40 involves a large cost of mold investment, which is a problem factor that must be considered. The corresponding microphone board 20 adapted sound port shown in Figure 3 (the black dot in the area marked by the dotted box in the figure is the sound port) is directly made on the frame profile 40.

[0074] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0075] Embodiment 1 of the present invention provides an interactive tablet, as shown in Figures 1 to 6 , including a support plate 1, a microphone circuit board 2, and a baffle 3, wherein:

[0076] The support plate 1 is provided with a notch 11 adapted for the microphone circuit board 2. At least a pair of latches 12 are positioned around this notch 11 to lock the microphone circuit board 2 within it. In Figure 1, the location and size of the notch 11 are specifically indicated by a dashed box. As can be seen from Figure 1, in one embodiment, the corresponding microphone circuit board 2 is formed into a rectangular structure. To this end, the embodiments of the present invention propose that the latches 12 are preferably positioned on either side of the rectangular microphone circuit board 2, near the short sides. As can be seen from Figure 1, to enhance the stability of the microphone circuit board 2, the beam structure supporting the microphone circuit board 2 in the corresponding notch 11 is designed to have a height difference relative to the surface of the support plate 1 housing on the side where the latches 12 are located, accommodating part or all of the height of the microphone circuit board 2. This utilizes the outer frame structure of the support plate 1 to further serve as an auxiliary structure to limit the vertical movement of the microphone circuit board 2. The vertical movement of the microphone circuit board 2 described here is with respect to the YOZ plane angle shown in Figure 1.

[0077] The support plate 1 and the baffle 3 are assembled and fixed on the frame profile 4 , and one or more sound collection holes 31 on the baffle 3 correspond to one or more sound collection holes 21 on the microphone circuit board 2 .

[0078] The exploded view of the interactive tablet in Figure 1 , the relative assembly view in Figure 5 , and the cross-sectional view in Figure 6 , taken along line A-A' in Figure 5 , do not depict a specific bezel profile 4. Instead, the description focuses solely on the structural adaptation relationship between the bracket plate 1 , microphone circuit board 2 , and baffle 3 , including the corresponding assembly view. Furthermore, the figures in this specification illustrate two microphone circuit boards 2 for example, and they are symmetrical. Therefore, to simplify labeling, some figures only label the relevant structures of one microphone circuit board 2. However, it is understood that the relevant structures of the other microphone circuit board 2 on the other side are also complementary. Furthermore, in actual implementation, the number of corresponding microphone circuit boards 2 is not limited to the two shown in the relevant figures; a combination of multiple microphone circuit boards 2 is also possible.

[0079] Regarding combined fixing, the present invention proposes a method in which the bracket plate 1 and baffle 3 are fixed to the inner and outer sides of the frame profile, respectively. The combined fixing of the bracket plate 1 and baffle 3 to the frame profile 4 is actually a relative spatial relationship. Specifically, the inner side of the frame profile 4 refers more to the structural area that is not visible to the user from the external environment, while the outer side of the frame profile 4 refers more to the structural area that the user can directly observe through the external display.

[0080] There are at least the following optional methods for fixing the above-mentioned bracket plate 1 and baffle 3 combination to the frame profile 4:

[0081] Method 1: The baffle 3 is fixed on the bracket plate 1 , and the bracket plate 1 is fixed on the frame profile 4 .

[0082] Method 2: The baffle 3 is fixed on the frame profile 4, and at the same time, the bracket plate 1 is also fixed on the frame profile 4, for example, by making one or more slots in the frame profile 4, and the corresponding slots are used to support the coupling structure between the bracket plate 1 and the baffle 3.

[0083] Method three: the bracket plate 1 is fixed on the baffle 3 , and the baffle 3 is fixed on the frame profile 4 .

[0084] The above three methods can be adapted and selected according to the actual assembly environment requirements. For example, method one is more suitable for operations such as maintenance, which facilitates the opening of the back cover. This is similar to the application scenario of a small screen. In this scenario, the baffle 3 is generally rarely made to be removable separately. The advantage of method one is that it takes into account both the concealment and stability of the installation and improves the integration of the components. Methods two and three are more suitable for large screens. The corresponding frame profiles 4 have the possibility of being disassembled and repaired from the front. In this case, although the component integration is reduced (that is, the bracket plate 1 and the baffle 3 are more likely to be stored and packaged separately for transportation, and cannot be assembled and used in advance like method one), they can bring more convenience in maintenance. Because, similar to the large screen scenario, it is more likely to be directly installed on the wall, and back maintenance operations are almost impossible. In this case, methods two and three can friendly support the disassembly and maintenance of the front of the screen. The drawings cited in the subsequent embodiments of the present invention are based on the above method two. On this basis, the implementation extended to methods one and three can be achieved by those skilled in the art without creative work and should be deemed to fall within the scope of protection of the present invention.

[0085] In terms of the specific implementation process of the solution, the microphone chip on the microphone circuit board needs to be able to collect sound, which requires that the sensing portion of the microphone chip be able to communicate with the outside world. Therefore, waterproofing is also a necessary and preferred feature of the present invention. As shown in Figures 1 and 6, a waterproof gasket 5 is also included. The waterproof gasket 5 is disposed between the microphone circuit board 2 and the baffle 3. The waterproof gasket 5 is provided with a transition hole 51. The sound collection hole 31 on the baffle 3, the sound receiving hole 21 on the microphone circuit board 2, and the transition hole 51 on the waterproof gasket correspond to each other.

[0086] As can be seen in FIG7 , which is an enlarged view of the left-hand side structure of FIG6 , the diameter of the sound receiving hole 21 on the microphone circuit board 2 is a first dimension (labeled d1 in FIG7 ), while the diameter of the transition hole 51 on the waterproof gasket 5 is a second dimension (labeled d2 in FIG7 ). The second dimension d2 is larger than the first dimension d1. This ensures that the deformation of the waterproof gasket 5 caused by the contact and compression between the microphone circuit board 2 and the baffle 3 does not cover or affect the sound receiving path of the sound receiving hole 21. Without the corresponding design, the impact would be minimal, such as designing the transition hole 51 to be the same diameter as the sound receiving hole 21. However, if the waterproof gasket 5 is squeezed and deformed, it would cause a certain degree of bending of the transition hole 51, causing more sound to be absorbed by the deformed inner wall of the transition hole 51. A more significant impact could occur, such as the deformation of the waterproof gasket material around the transition hole 51, blocking the corresponding sound receiving hole 21, significantly reducing the sound receiving effect. In the actual implementation process, the values ​​of the corresponding first dimension d1 and the second dimension d2 will be affected by many factors such as the model of the microphone chip, the size of the microphone circuit board 2, the deformation of the waterproof gasket 5, etc., and there will be different point combinations and values. The present invention is to explain the logical relationship between the two. The actual value can be completed according to the specific situation to ensure that the deformation area of ​​the corresponding waterproof gasket 5 does not affect the sound reception. It is not expanded on too many parameter levels here.

[0087] In order to further improve the waterproof effect, considering that the baffle 3 may be deformed during installation and fixation in actual situations, as well as the surface flatness and stress consistency during its own processing, if the sound collection hole 31 on the baffle 3, the transition hole 51 of the waterproof gasket 5 and the sound receiving hole 21 of the microphone circuit board 2 are directly adapted to effectively prevent liquid water from entering other electrical areas on the microphone circuit board 2 through the sound collection hole 31, there will still be a risk. To this end, the present invention also provides an improved solution:

[0088] As shown in Figures 8 and 9 , an annular boss 32 is provided around the sound collection hole 31 of the baffle 3 on the side facing the waterproof gasket 5. The surface of the annular boss 32 abuts the waterproof gasket around the transition hole 51. The outer diameter of the annular boss 32 is a third dimension (denoted as d3 in Figure 9 ), which is greater than the second dimension d2. The specific relationship between the third dimension d3 and the second dimension d2 is designed based on actual scenario requirements. The difference in size between the two dimensions is preferably such that the surrounding area of ​​the transition hole 51 of the waterproof gasket 5 can still be effectively abutted by the surface of the annular boss 32 after being squeezed and deformed. At this point, those skilled in the art have already completed the design of supporting parameters based on actual scenario requirements, so we will not elaborate on these parameters here.

[0089] If the implementation processes shown in Figures 1 to 8 are all described in the form of directly assembling the bracket plate 1, microphone circuit board 2 and baffle 3 into an interactive flat panel, then in real application scenarios, the above-mentioned method 2 will also be encountered. In the case where the baffle 3 has an annular boss 32, the annular boss 32 is usually reused, that is, as shown in Figures 10 and 11, a fixing through-hole 43 adapted to each annular boss 32 is provided on the frame profile 4, so that the baffle 3 can play a better role in limiting the position when the baffle 3 is installed and fixed on the frame profile 4. It is not difficult to find from Figure 11 that the corresponding fixing through-hole 43 on the frame profile 4 can be set according to demand and is not greatly affected by the existing version structure of the frame profile itself. However, once a layer of frame profile 4 is inserted between the support plate 1 and the baffle 3 (as shown in FIG12 , which is a schematic diagram of the effect after the support plate 1 and the baffle 3 are assembled with the frame profile 4), the waterproof effect around the sound receiving hole 21 already established as shown in FIG6 and FIG7 will be affected. Therefore, the present invention also proposes an improved solution that can further optimize the above situation, as follows:

[0090] As shown in Figures 13 and 14, Figure 13 can be understood as a rendering of the same sectional angle as Figure 6, with the reinforcing ribs in the bracket plate 1, which are not of great importance, hidden. When the interactive flat panel is installed on the frame profile 4, the waterproof gasket 5 and the baffle 3 are separated by the frame profile 4, and the frame profile 4 is located in the area between the waterproof gasket 5 and the baffle 3 and is provided with through holes 41 that are adapted to the number of annular bosses 32; wherein, the diameter d4 of the through hole 41 is greater than or equal to the outer diameter d5 of the annular boss 32 (see the corresponding identification object in Figure 13 for details), and the height h2 of the annular boss 32 exceeds the preset value compared with the thickness h1 of the frame profile plate that carries the through hole 41. The preset value here is usually between 0.5-1.5mm, and will also be determined by reference to the deformation space of the corresponding waterproof gasket 5 during actual operation, because the excess part here is the waterproof gasket material used to abut against the transition hole 51 around the waterproof gasket 5, forming an effective waterproof effect in the area other than the transition hole and the corresponding sound collection hole 31 and the transition hole 51.

[0091] As one of the important components and features of the embodiment of the present invention, the bracket plate 1 is provided with a slot 11, and its structural feature design also has corresponding optimization examples, which is manifested as follows: the depth of the slot 11 makes the upper surface D of the locked microphone circuit board 2 located below the frame surface C of the bracket plate 1 (refer to the surface C and surface D marked by arrows in Figure 13), so that the body of the corresponding microphone circuit board 2 can be protected in the outer shell of the bracket plate 1; on the other hand, the surface of the waterproof gasket 5 used to abut against the baffle 3 is higher than the end of the buckle 12 on the bracket plate 1 by a second preset value d6 (since the bayonet 12 is not shown in Figure 13, Figure 7 is borrowed and d6 is marked in Figure 7). The surface of the waterproof gasket 5 used to abut against the baffle 3 is higher than the end of the buckle 12 on the bracket plate 1 by a second preset value d6, so as to directly avoid the situation where the end structure of the buckle 12 may abut against the baffle 3 or the frame profile 4 through the thickness of the waterproof gasket 5.

[0092] As one of the important components and features of the embodiment of the present invention, the buckle 12 in the bracket plate 1 also provides a preferred implementation method in the embodiment of the present invention. As shown in Figure 15, the buckle 12 includes a first buckle 121 and a second buckle 122, wherein the first buckle 121 and the second buckle 122 are respectively formed by extending the frame of the bracket plate 1; the elastic arms of the first buckle 121 and / or the second buckle 122 are formed by setting a pair of notches 123 in the frame. The above-mentioned extension formation is generally understood to be cast together with the bracket plate 1 through a mold; and the setting of the above-mentioned notch 123 is mainly to increase the elastic interaction space of the first buckle 121 and / or the second buckle 122, thereby improving the smoothness and convenience of the installation process of the corresponding bracket plate 1. As shown in Figure 15, it can also be found that in the specific example, at the end of the bracket plate 1 where the second clip 122 is located, in order to show the compactness between the microphone circuit board 2 and the baffle 3 after combination, the above-mentioned combination notch 123 is used to effectively optimize the effect; and for the first clip 121 located on the middle side of the bracket plate 1, the increase in its elastic interaction space can be achieved directly by reducing the height of the shells on both sides adjacent to the first clip 121 (the shell height here is the length of the dimension of the outer wall of the bracket plate 1 in the x-axis direction shown in Figure 15), that is, the height of the shells on both sides adjacent to the notch 123 is directly reduced to the bottom end of the elastic arm of the clip 121 (this can be more clearly observed through the symmetrical structure corresponding to the first clip 121 on its left side in Figure 15).

[0093] During the implementation of the present invention, it was considered that multiple microphone chips may be mounted on a single microphone circuit board 2. Furthermore, the increasingly narrow frame thickness of the frame profile 4, which is required for manufacturing, has led to the corresponding evolution of the microphone circuit board 2 into an increasingly slender strip structure. Therefore, when only the clip 12 is used to secure the microphone circuit board 2, warping of the microphone circuit board 2 may occur. To address this situation, the present invention provides an optimized solution, which is implemented as follows:

[0094] As shown in Figure 16, at least one limiting column 13 is provided at a preset position on the slot 11 in the bracket plate 1. When the microphone circuit board 2 is locked in the slot 11, the limiting column 13 passes through the limiting hole 22 provided at the corresponding position on the microphone circuit board 2.

[0095] During the implementation process, in order to achieve a better limiting effect, referring to Figures 17 and 18, the limiting column 13 is a double elastic arm structure formed in the middle of the column near the end area, wherein the end of the elastic arm on one side of the double elastic arm structure is provided with an undercut.

[0096] At this point, it's necessary to analyze why the undercut structure employed in the embodiment of the present invention avoids the issue of easily damaged buckles 50, as shown in FIG1 . The reason is that the buckle 50, as shown in FIG1 , must both fully lock the corresponding microphone board 20 (i.e., the function of the buckle 12 in the embodiment of the present invention) and limit the warping deformation of the corresponding microphone board 20 (i.e., the function of the limiting post 13 in the embodiment of the present invention). Therefore, it employs a structure in which both elastic arms of a single buckle 50 are undercut. For example, the buckle in FIG1 employs a structure with a larger undercut at the end to enhance its locking force. However, this reduces the strength of the two elastic arms. To maintain this strength, the buckle 50 must be made larger, which conflicts with the objective reality of the relatively small aperture in the microphone board 20. Ultimately, a compromise is forced, reducing the strength of the two elastic arms of the buckle 50 to accommodate the aperture in the microphone board 20. This, in turn, leads to the technical issues previously analyzed in Example 1.

[0097] However, the embodiment of the present invention combines the aforementioned buckle 12 with a retaining post 13, effectively eliminating the shortcomings of the buckle 50 in FIG. 1 . This is because the locking mechanism is already implemented by the buckle 12. The retaining post 13 only needs to prevent the microphone circuit board 2 from warping. This reduces the need for undercuts at the ends of the two elastic arms in FIG. 1 to only one of the two elastic arms. This allows the gap between the two elastic arms to be used by the undercut, rather than by both arms, as shown in FIG. 1 . The reason for this has been explained above: the undercut in FIG. 1 needs to serve a dual purpose, requiring a sufficiently large lateral extension. However, this reduces the strength of the two elastic arms. To meet the aperture requirements of the microphone board 50 in FIG. 1 , the size of the two elastic arms needs to be reduced to allow for the lateral extension of the undercut.

[0098] In order to more intuitively show the structural feature of the above-mentioned undercut made on one side of the end of the double elastic arms, Figure 18 is now used as a structural detail diagram to elaborate on the relevant structural details. Referring to Figure 17, as shown in Figure 18, for a single microphone circuit board 2, when the number of its limiting holes is 2, the limiting column 13 includes a first limiting column 131 and a second limiting column 132, and the corresponding first elastic arm 1311 and second elastic arm 1312 of the first limiting column 131, and the third elastic arm 1321 and fourth elastic arm 1322 of the second limiting column 132. The four elastic arms are arranged in a line, and the first elastic arm at both ends of the arrangement relationship is provided with an undercut 1313 and the fourth elastic arm is provided with an undercut 1323, and the directions of the undercut 1313 and the undercut 1323 are exactly opposite. Taking Figure 18 as an example, the undercut 1313 is facing the left side in Figure 18, while the undercut 1323 is facing the right side in Figure 18. The advantage of such a design is that, although only the first elastic arm 1311 of the double elastic arms and the fourth elastic arm 1322 of the other limiting column are used with respect to a single limiting column, the orientation of the undercut 1313 and the undercut 1323 of the two can make the interaction force of the undercut 1313 and the undercut 1323 on the microphone circuit board 2 play the role of a buckle 50 in the original Figure 1. However, as shown in FIG18 , the embodiment of the present invention adopts the method of making undercuts on the first elastic arm 1311 and the fourth elastic arm 1322 which are far away from and opposite to each other on the two limiting posts 13 applicable to one microphone circuit board 2, while the other second elastic arm 1312 and the third elastic arm 1321 of each limiting post 13 are made into a smooth structure without undercuts. In this way, as shown in FIG18 , each time the microphone circuit board 2 is installed in the slot 11 of the bracket plate 1, the deformation of each elastic arm in the corresponding two limiting posts 13 is as shown in FIG18 , and when the second elastic arm 1312 and the third elastic arm 1321 are not deformed much, the first elastic arm 1 The gap space between 311 and the second elastic arm 1312, as well as the gap space between the third elastic arm 1321 and the fourth elastic arm 1322, are respectively reserved for the space required for the undercut on the first elastic arm 1311 and the undercut on the fourth elastic arm 1322 to deform when they abut against the limiting hole 22 of the microphone circuit board 2 (the deformation effect as shown in Figure 19). In this way, while ensuring the strength of the corresponding limiting column 13 itself, it provides an improvement means for the problem that the buckle 13 on the bracket plate 1 may warp due to the long microphone circuit board 2 after being fixed, and also avoids the problem that the buckle 50 structural component is not strong enough and is easy to deform or break, as described in the previously cited Figure 1.

[0099] Figures 16 to 19 illustrate an optimized solution for adding a limit post 13 to the bracket plate 1. However, as a complete solution, once the corresponding limit post 13 structure is set, the undercut structure provided in the matching limit post 13 will extend beyond the outer surface of the corresponding microphone circuit board 2 (wherein the side of the microphone circuit board 2 facing the bracket plate 1 is understood as the inner surface, and the other side is the outer surface) by a certain distance after the microphone circuit board 2 is installed and fixed. In this case, it is necessary to make matching adjustments to the waterproof gasket 5 that is directly assembled with the outer surface of the microphone circuit board 2. Specifically, as shown in Figure 20, a receiving hole 52 is provided on the waterproof gasket 5. After the undercut 1313 provided on the first elastic arm 1311 and the undercut 1323 provided on the fourth elastic arm 1322 buckle the microphone circuit board 2, the receiving hole 52 is used to support the undercut 1313 and the portion that extends beyond the surface of the microphone circuit board 2.

[0100] When expanded to the technical solution shown in FIG. 20 , the corresponding embodiment of the present invention includes the following number of holes: the sound receiving hole 21 on the microphone circuit board 2, the sound collecting hole 31 on the baffle 3, and the transition hole 51 on the waterproof gasket 5 for sound reception; and the limiting hole 22 on the microphone circuit board 2 and the accommodating hole 52 on the waterproof gasket 5 for mounting with the limiting post 13. With this design, the accommodating hole 52 and the transition hole 51 on the waterproof gasket 5 also require associated parameter constraints to prevent the proximity between the accommodating hole 52 and the transition hole 51 from affecting the final waterproofing effect of the microphone circuit board 2. Therefore, the distance between the accommodating hole 52 and the adjacent transition hole 51 exceeds a second preset threshold. The second preset threshold here is determined by the deformation of the corresponding waterproof gasket 5 under pressure and the third dimension d3 of the outer ring diameter of the corresponding annular boss 32. The purpose is to prevent the waterproof gasket material around the corresponding transition hole 51 from being pushed toward the surrounding area of ​​the abutment area of ​​the annular boss 32 when the annular boss 32 abuts the transition hole 51. At this time, if the distance between the corresponding adjacent receiving holes 52 and transition holes 51 is too small, the above-mentioned pushing process may cause a gap in the waterproof material between the receiving holes 52 and the transition holes 51, affecting the waterproof effect. In the application example of the product of the present invention, the second preset value parameter here is 1.5-5mm, which can usually meet the application requirements of many occasions. However, this specific parameter value should not limit the protection scope that the deep technical characteristics proposed by the second preset threshold should have.

[0101] As an embodiment of the present invention, considering that the weight of the interactive flat panel itself also needs to be developed and optimized to the greatest extent, therefore, in the interactive flat panel structure proposed in the embodiment of the present invention, an improvement scheme is also proposed for the shell structure of the bracket plate 1 itself.

[0102] As shown in FIGS. 20, 21 and 22, where FIG. 22 is a sectional structural view of the section line B-B' in FIG. 21. It can be seen from FIGS. 20 and 22 that the support plate 1 is composed of various reinforcing ribs to form an internally hollow shell type. Among them, the second limiting column 132 is close to the middle area of the support plate, and the first limiting column 131 is close to the end area of the support plate 1.

[0103] The second limiting column 132 is a hollow column. The first side of the outer wall of the hollow column is directly coupled to the outer surface of one side of the support plate 1 through a strip-shaped reinforcing rib (directly shown in FIG. 22), and the second side is coupled to the outer surface of the other side of the support plate 1 through another strip-shaped reinforcing rib; among them, together with the second limiting column 132 body and the reinforcing ribs on both sides, they jointly form the common side of two adjacent cross-shaped reinforcing rib structures. The two adjacent cross-shaped reinforcing rib structures here are marked by two adjacent square dotted lines in FIG. 22. It can be seen from FIG. 22 that the upper and lower surfaces of the corresponding cross-shaped reinforcing rib structure reuse the outer frame material of the support plate 1, and it can also be seen that the outline of the cross-shaped one on the left is not a standard font. Here, the description as cross-shaped is mainly a more vivid description method starting from its structural form. In FIG. 22, there is a concave figure (described as avoiding figure 15 in the subsequent embodiment) at the lower left of the cross-shaped reinforcing rib on the left, and the corresponding concave figure is for structural adaptation to the wiring interface 24 described in the subsequent development of the embodiment of the present invention, which will not be expanded here.

[0104] The first limiting column 131 is a hollow column. The two sides of the hollow column are respectively coupled to the opposite two side surfaces of the support plate 1 through strip-shaped reinforcing ribs. Different from the second limiting column 132 being close to the central area, the first limiting column 131 is close to the end of the support plate 1, and its strength design is much lower than that of the central area. Therefore, a comb-shaped reinforcing rib structure similar to that shown in FIG. 20 is adopted. Correspondingly, it can also be observed in the area marked by the elliptical dotted line in FIG. 22.

[0105] Through the above set of ingenious reinforcing rib structure designs, the tabletop structure for supporting the microphone circuit board 2 under the slot 11 of the corresponding microphone circuit board 2 is also formed. The gaps of the corresponding reinforcing ribs can be used to accommodate the chip parts of the microphone circuit board 2 that are not easy to reduce in height individually; and in the embodiment of the present invention, the strength of the limiting column 13 itself included is also used as an intermediate part connecting the reinforcing ribs, saving the use of the material itself without loss of strength.

[0106] As shown in Figure 23, as another ingenious design of an embodiment of the present invention, the height of the end of the limit column 13 is the same as the height of the end of the buckle 12. The significance here is that when there is a waterproof gasket 5 between the baffle 3 and the bracket plate 1, the direct contact point between the two still falls on the waterproof gasket 5; however, when designing the structure, it is necessary to consider that the baffle 3 may be impacted by external forces. At this time, it is necessary to design a matching force dissipation solution for the corresponding random external force generation points. Among them, if a single contact point with the baffle 3 appears on the bracket plate 1 or the microphone circuit board 2 when an external force is generated, it is very likely that the contact point structure will cause a large deformation, affecting the structural stability of the device. Taking the above-mentioned factors into consideration, the design is that the end height of the above-mentioned limit column 13 is the same as the end height of the clip 12. This is because the number of limit columns 13 increases with the length of the microphone circuit board 2 and is distributed on the microphone circuit board 2. The corresponding clips 12 are located at both ends of the bracket plate 1 and cooperate with the limit columns 13 to almost construct the above-mentioned highest priority contact point with the baffle 3. Therefore, setting their heights to be consistent is conducive to spreading and dissipating the external impact force from the baffle 3.

[0107] As mentioned above in the analysis of the cable interface 24 in the reinforcement structure in conjunction with Figure 22, the improvement scheme designed for the corresponding cable interface 24 in an embodiment of the present invention will be explained here in conjunction with Figure 24, in order to improve the corresponding cable after the bracket plate 1 and the microphone circuit board 2 are assembled, and the cable interface 24 can still be easily plugged and unplugged.

[0108] As shown in Figures 24 to 26, the cable interface 24 of the microphone circuit board 2 is made in the middle and close to one side frame. The bracket plate 1 is provided with a avoidance figure 15 in the frame for the cable interface 24. The avoidance figure 15 is made according to the shape of the cable interface. After the microphone circuit board 2 is installed on the bracket plate 1, the bracket plate 1 exposes the cable interface 24 outside the slot 11 of the bracket plate 1 through the avoidance figure 15. From Figures 25 and 26 , it can be seen that the avoidance figure 15 is formed by directly making a groove on the outer shell of the corresponding bracket plate 1 that can accommodate the cable interface 24 (usually it will be made into a rectangular groove), and a cable limiting protrusion 16 is also made on the side of the avoidance figure 15 adjacent to the cable outlet. As shown in Figure 26 , the corresponding cable limiting protrusions 16 are arranged in pairs, and the gap between the relatively arranged limiting protrusions 16 is slightly smaller than the width of the cable, so that the corresponding cable can be embedded in the limiting groove constructed by the limiting protrusion 16 through appropriate deformation, without being able to easily detach from the limiting protrusion 16.

[0109] In order to further ensure the unilateral sound receiving characteristics of the corresponding microphone chip and its own waterproof characteristics on the inner side of the bracket plate 1, the microphone chip on the corresponding microphone circuit board 2 is usually improved as follows:

[0110] As shown in Figure 24, the sound receiving hole 21 on each microphone circuit board 2 matches the sound collecting hole 31 on one side, and a microphone chip is located on the other side. Each microphone chip is covered on all sides by a soft rubber cap 23, the top of which contacts the reinforcing rib structure on the bracket board 1. As shown in Figure 27, when the four soft rubber caps 23 included on the microphone circuit board 2 shown in Figure 24 are presented in the interactive tablet application scenario of Figure 27, they are each matched to the corresponding square reinforcing rib structure 17 in the figure.

[0111] As shown in FIG24 , in order to ensure that the microphone circuit board 2 with the soft rubber cap 23 added can still be stably placed in the notch 11 of the bracket plate 1, a preferred solution is: a pad 25 is made on the microphone circuit board 2 around the soft rubber cap 23, and the pad 25 abuts against the base of the notch 11 of the bracket plate 1. The pad 25 is generally a hollow structure, and its internal hollow area can be used to accommodate other electrical components on the microphone circuit board 2, such as resistors, capacitors, other integrated circuits, etc. The pad 25 can also be fastened to the microphone circuit board 2 by snapping, bonding, or even, when the pad 25 is made of metal, it can be fixed to the bottom plate of the microphone circuit board 2 by welding. The thickness of the pad 25 is usually designed to be larger than the thickness of the soft rubber cap 23. This makes it easier to design the square reinforcement rib structure 17 to protrude a certain distance from the bottom of the notch 11, thereby forming a better elastic abutment effect on the soft rubber cap 23.

[0112] As shown in Figure 28, in combination with the embodiment of the present invention, a relatively simple way is provided for how the baffle 3 is coupled and fixed with the frame profile 4. As shown in Figure 28, a lock 32 is provided near the upper and lower edges of the baffle 3. The lock 32 passes through the preset lock hole 42 on the frame profile 4 and is tightly fastened to the frame profile 4.

[0113] As shown in Figure 28, in combination with the embodiment of the present invention, a relatively simple way is provided for how the bracket plate 1 is coupled and fixed with the frame profile 4. As shown in Figures 26 and 27, the bracket plate 1 is fixed to the threaded column located on the inner side of the frame profile 4 by screws, or the bracket plate 1 is fixed to the inner side of the frame profile 4 by locking.

[0114] The examples shown in Figures 1-27 above all illustrate a configuration in which two microphone circuit boards 2 are symmetrically arranged on either side of the support plate 1. As a possible implementation, depending on the actual scenario, the support plates 1 are not limited to being arranged in a straight line as shown in the above figures; they may also adopt a concave shape, other curved shapes, and so on. The number of microphone circuit boards can also be varied or simplified in different scenarios.

[0115] As shown in Figures 27 and 28 , as an optional solution in an embodiment of the present invention, a camera assembly mounting slot is provided in the middle area of ​​the bracket plate 1. The corresponding mounting slots are marked with dotted boxes in Figures 27 and 28 . Since the configuration of the camera assembly is only an expansion combination implementation solution supported by the embodiment of the present invention and is not the focus of the improvement of the present invention, only the corresponding spatial structural position relationship is provided.

[0116] As shown in FIG. 29 and FIG. 30 , the frame profile 4 includes one or more of a television frame, a conference room LED large screen frame, and a billboard large screen frame.

[0117] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
